摘要： A solar cell includes a first conductivity type crystalline semiconductor substrate, a first amorphous silicon region, a first electrode, and a second electrode. The crystalline semiconductor substrate may include a plurality of pyramidal-shaped projections or a plurality of reverse-pyramidal shape depressions on at least one surface thereof. The first amorphous silicon region may be positioned on the crystalline semiconductor substrate and have a second conductivity type opposite the first conductivity type. The first electrode may be positioned on the first amorphous silicon region, and a second electrode positioned on the substrate. At least one pyramidal-shaped projection or at least one reverse-pyramidal shape depression may include two adjacent inclination surfaces, and a rounded edge portion where the two adjacent inclination surfaces meet.
